Another bustling day across the React, TanStack, and Next.js ecosystems. Here's what the core engineers were up to in the last 24 hours.

@acdlite — Andrew Clark

Andrew opened a notable PR in Next.js introducing a new primitive for coordinating client fetches:

• 🆕 instant(): Block out-of-band client fetches — a fresh PR in vercel/next.js.

He also chimed in on several React internals threads:

• 💬 Update tests for prefetch inlining (1/n)
• 💬 Fix form status reset when component state is updated
• 💬 Transition Tracing Offscreen Tree Deletion
• 💬 Implement react-server-dom-rspack — RSC support for Rspack is cooking.

@gaearon — Dan Abramov

A quiet day. No public activity.

@sebmarkbage — Sebastian Markbåge

Sebastian was reviewing React core PRs:

• 💬 Fix form status reset when component state is updated
• 💬 Fix propagation of legacy context when used with memo

@tannerlinsley — Tanner Linsley

Tanner had a very productive day on the TanStack side — three PRs merged and a bunch of review activity:

• 🆕 feat(shop): redesign /shop pages with editorial theme and Tailwind primitives
• 🆕 fix(deps): bump @tanstack/dom-vite to 0.1.0-alpha.7
• 🆕 fix(search): exclude Configure from devtools source injection
• 💬 feat: admin framework adapter pattern and tanstack support — reviewing a Payload CMS integration.
• 💬 Output ES module from rollup
• 💬 fix(create): generate minimal scaffolding when declining demo/example pages
• 💬 docs: correct broken hyperlinks in README.md
• 💬 fix: multiple mutations not calling callbacks each time
• 💬 Fix setQueryData crash
• 💬 Prevent re-run of query for refetch interval if update is disabled

@leerob — Lee Robinson

• 💬 fix(image): callback should be updated during layout effect

@timneutkens — Tim Neutkens

Tim was triaging Next.js PRs:

• 💬 fix: preserve Request body source in patch-fetch
• 💬 change the process name of builds

@bvaughn — Brian Vaughn

A quiet day. No public activity.

@t3dotgg — Theo Browne

A quiet day. No public activity.

@TkDodo — Dominik Dorfmeister

Huge day from Dominik over at Sentry — five PRs opened and plenty of review work:

• 🆕 fix(workflowEngine): use primary border color
• 🆕 ref(tsc): invoices endpoint to apiOptions (draft)
• 🆕 ref(tsc): issues endpoint to apiOptions
• 🆕 ref(pageFrame): move texts into subTitle of SettingsPageHeader
• 🆕 fix(pageFrame): render settings layout subtitle
• 💬 ref(layout) use layout.main
• 💬 fix(eslint): used extends for remaining plugin configs
• 💬 fix(automations): keep alert titles in page layout
• 💬 fix(forms): propagate request field errors in autosave
• 💬 ref(stories): automatic categories via index
• 💬 fix(issue-details): Keep sticky event nav below page frame
• 💬 feat(project-filters): Simplify All/My Projects toggle

@phryneas — Lenz Weber-Tronic

• 💬 Enforce global type declaration for defaultOptions
• 💬 Security: bare mui npm namespace held by third party — baitsquatting risk — an interesting supply-chain security discussion.

@markerikson — Mark Erikson

A quiet day. No public activity.

@kettanaito — Artem Zakharchenko

Heavy MSW maintenance day:

• 💬 Support updates through getters
• 💬 v1.1.2: "One-to-many (inversed)" not working as documented
• 💬 v1.1.2 Not able to use update() to add entry into many() relation
• 💬 msw-storybook-addon: per-story handlers on Docs tab
• 💬 Make sorting configuration an array instead of an object
• 💬 fix: support an array as the orderBy value

@dinwwwh — dinwwwh

• 💬 feat(server,openapi): support ReadableStream<Uint8Array> as handler return value
• 💬 Support return ReadableStream<binary> in .handler

Today's Highlight

The standout item today is acdlite's instant() PR in Next.js — a new primitive designed to block out-of-band client fetches. Combined with ongoing review activity on react-server-dom-rspack, it's clear the React team is deep in the weeds of tightening data-fetching semantics for the modern RSC era.

Meanwhile, Tanner is giving the TanStack shop a fresh editorial redesign, and TkDodo is methodically migrating Sentry's frontend to typed apiOptions — a reminder that the less glamorous refactor work is where production codebases really earn their keep. 🛠️
